Which system acts as an adjunct to surfactant cleaning to remove stubborn deposits?

• A. Enzyme and protein removers
• B. Disinfecting wipes
• C. Polyquad-based cleaners
• D. Ultraviolet cleaners

Answer: (A)

Stubborn deposits on gas permeable lenses are often protein-based and don’t fully come off with surfactant cleaning alone. Enzyme and protein removers provide an enzymatic action that breaks down these proteins—like lysozyme and other tear proteins—so the deposits are turned into smaller, rinseable fragments. They’re used as an adjunct to regular cleaning, usually as a separate soak for several hours or overnight according to product instructions, rather than as a daily substitute for rubbing with a surfactant cleaner. This approach helps keep lenses clear and comfortable by tackling deposits that resist ordinary cleaning. Other options in the list focus on disinfection or UV sterilization and aren’t directed at removing protein deposits from the lens surface. Remember to follow the product guidelines and rinse thoroughly after enzyme cleaning.
